What Brown and Mason does
Brown and Mason Group Limited is a privately held UK industrial services company founded in 1961, headquartered in Dartford, Kent, with a directly employed workforce of 500+ personnel. The company specializes in heavy industrial demolition, dismantling, decommissioning, decontamination, and asbestos removal, positioning itself as one of Europe's largest contractors in this sector. Its core offerings span a turnkey service model covering preconstruction advice, licensed asbestos removal, controlled explosive demolition (via an in-house explosives engineering team), industrial dismantling, asset recovery/scrap metal reclamation, excavation and remediation, and niche capabilities in marine and nuclear decommissioning. Underlying technology centers on a continuously reinvested plant fleet ranging from 1-tonne mini excavators to 110-tonne high-reach excavators with concrete crusher attachments, supplemented by explosive engineering expertise.
The company generates revenue through project-based professional services contracts, priced individually per scope, complexity, and duration, with multi-year contract cadence typical. It operates an exclusive direct enterprise sales motion targeting power generation operators, industrial manufacturers, chemical/refinery owners, and utilities infrastructure holders. Its customer base is dominated by large UK and European energy corporates including EDF Energy, Scottish Power, Engie, E.ON UK, National Grid Property Holdings, and Northern Ireland Electricity, with project work spanning the UK, Netherlands, and Hungary. Notable project scale includes the Cottam Power Station demolition (scheduled for completion in early 2026), a Guinness World Record for simultaneous explosive demolition of 8 cooling towers, and what is described as Europe's largest asbestos removal contract at 35,000 m³.
The business operates from three UK sites: the Dartford headquarters (estimating, tendering, QA, accounts), a Broadstairs plant and fleet maintenance depot, and a newly established offshore decommissioning base at Dales Voe, Lerwick Harbour in Shetland (launched July 2025 through partnerships with Peterson Energy Logistics and Lerwick Port Authority). Brown and Mason maintains membership in industry bodies including the National Federation of Demolition Contractors (since 1961), the Asbestos Removal Contractors Association (since 1996), and the European Demolition Association (since 2020), and has won multiple British Demolition Awards and British Safety Council Five Star/Sword of Honour accolades.
